WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 763,747, dated June 28, 1904.

Applicata.. ned March 2s, 1904.`

.To ad w/wm t may concern.:

- Be it known that I, ALVIN CAROLL Gon- DARD, a citizen of the United States, and a resident of Woodcliif, in the county of Hudson and State of New Jersey, have invented `a new and Improved VVindow-Sash, of which the following is a full, clear, and eXact description.

This invention relates particularly to that class of window-sash adapted to slide vertically in the window-casing and to swing on horizontal pivots, so that the sash may be turned to any desired angle or completely reversed for convenience in washing both sides ofthe glass by a person within the room; and the object is to provide a simple mechanism permitting the movements with ease and without noise.

A further object is to provide a novel means for attaching the sash-chains to the sashes.

Other objects of the invention will appear in the general description.

I will describe a window-sash embodying my invention and then-point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation, partly in seotion, of a window-sash and attachment ernbodying my invention. Fig. 2 is a sectional elevation thereof. Fig. 3 is a sectional detail showing the means for attaching a chain to the sash. Fig. 4 is an elevation thereof. Eig. 5 is a section on the .line .fr a: of Fig. 1. Fig. 6 is a similar section, but showing the sash as swung on its pivots. Fig. 7 is a sectional detail showing the means for locking the guide-strips at certain times;t Fig. 8 is a face view showing a modified means for attaching the chains, and Fig. 9 is a sectional view thereof.

Referring to the drawings, 1 designates the lower sash, and 2 the upper sash, both operating in the window-casing 3. As the connections between the casing and both sashes are alike, a description of one will answer for both. It may be here stated that practically the usual form of sash is employed, it being Serial No. 199,527. (No model.)

a trifle narrower, however, than the usual sash, and therefore no special mechanism is required for the construction.

ArrangedA at both sides of the casing within the channels formed between the stop-bead I and the stop-strips are guides 5, which, as here shown, consist of metal; but it is to be understood that they may be made of wood. Each guide-strip has a central vertical channel 6, and at the sides thereof are ribs 7 for engaging in correspondingly-shaped channels 8, formed in the side rails of the sash. It will be noted that the opposite sides of the ribs 7 are inclined or cam shaped, the object of which will hereinafter appear. The guidestrips are held yieldingly against the sash by means of plate-springs 9, secured to the window-casing and engaging at their ends with the said strips. While I have shown three of these springs, one at the top, one at the bottom, and one at about the center, it is obvious that more may be employed, if desired. The inward movement of the strips is limited or regulated by stop-screws 10, which engage in the casing and abut against the inner sides of the strips. When the sash is raised, turned,

lor entirely removed, it may be necessary to lock the vlower end of the guide-strips from outward movement. For this purpose I provide latch-hooks 11, having swinging connection with the lower portion of the casing and extended through openings 12 in the guidestrips. By forcing the lower portion of the guide-strips inward the hook portion of the latch will engage with the outer side of the lower wall of the openings 12, and when it is desired to release the same it is only necessary to raise the outer end of the latch.

Slidable in the channel 6 of each guid e-strip is a device for attachment to the sash and also for attachment to the weight-chain. This device consists of aboxing 13, open at its inner side and also having an opening at the top and an opening at the bottom. At the lower opening there are inwardly-extended flanges 14 for engaging with the sides of a lower link of the chain 15. These links, it will be noted, are substantially triangular in form, with the wider portions downward, so they will wedge in between the flanges 14. The chains are further attached to the boxings by means of lugs 16 17, one near the bottom and the other near the top, these lugs passing through links of the chain. By this construction the chain may be readily attached or detached. It will be understood, of course, that the chains pass over the usual pulleys at the top of the sash and connect with weights.

Extended outward from the boxing 13 is a sash-attaching lug 18,designed to pass through a keyhole-shaped opening 19,formed in a plate 20, attached to the side rail ofthe sash. The lug 18 has a projection 21, adapted to pass through the reduced portion of the opening 19. readily removed by reversing the same, so as to bring the narrow portion of the opening' 19 downward and in line with the downward projection 21 of the lug. By pressing the guide-strip inward the lug will be moved out through the opening. Inward of the plate the side rail is provided with a recess 22, permitting a free swinging movement around the lug and its projections.

In the operation the sash may be readily slid up and down in the usual manner, the guide-strips being' held in their outer positions against the sash. When it is desired to swing the sash on its pivotal lugs, it is only necessary to draw the upper or lower end outward, and the inclined or cam-shaped edges of the ribs 7 by engaging with the corresponding side walls of the channels 8 will cause the guide-strips to be pressed inward against the resistance of the springs 9. The parts will then be in a position substantially as indicated in Fig. 6.

In Figs. 8 and 9 the chain-attaching device consists of a boxing 23, the side walls of thechannel therein being provided with notches 24, conforming to the chain-links, and these notches extend in opposite directions from a center block 25, with which a screw-lug 26 engages and serves the same purpose as the lug 18.

Having thus described myinvention,I claim as new and desire to secure by Letters Patentw 1. The combination with a window-sash and a window-frame, of guide-strips arranged in the side channels of the frame, springs arranged in the channels for pressing the guidestrips outward, the said guide-'strips having vertical channels and vertical ribs at the sides of the channel, the sash being provided with channels to receive said ribs, chainattaching devices movable in the channels of the guidestrips, and pivotal connections between said devices and the sash.

2. The combination with a window sash and By this arrangement the sash may bev frame, ot' vertically-disposed spring-pressed guide-strips at opposite sides of the frame, the said guide-strips having central vertical channels and ribs at the opposite sides of the channels the side walls of said ribs being inclined, the side rails of the sash being provided with channels shaped to said ribs, chain-attaching devices movable in the channels of the guidestrips, and pivotflugs carried by said devices and having removable engagement with the side rails of the sash.

3. The combination with a window sash and frame, of spring-pressed guide-strips at opposite sides of the frame, the said guide-strips having central vertical channels and ribs at the opposite sides of the channels, the sash side rails having channels for receiving said ribs, boxes movable in the channels of the strips open at the inner side and also having openings at the top and bottom, iianges extended inward from the lower end of the boxes, a chain having links adapted to wedge between said flanges, lugs in the boxes for engaging in other links of the chain, and pivotlugs on the boxes having connection with the side rails of the sash.

4i. The combination with a window sash and frame, of guide-strips arranged between the stop-bead and stop-strips of the frame, springs arranged between said stops and pressing against the inner sides oi' the guide-strips, means for limiting the inward movement of the guide-strips, the said guide-strips having vertical channels and vertical ribs at the sides of the channels, the sash being provided in its side rails with channels to receive said ribs, chain-attaching devices movable in the channels of the guide-strips, plates attached to the side rails ofthe sash and having keyhole-openings, and lugs attached to the chain-attaching devices and having downward projections adapted to pass through said keyhole-openings.

5. The combination with a window sash and trame, of guide-strips arranged in the spaces betweenk the stop-beads and stop-strips of the frame, springs for pressing the guide-strips outward, chain-attaching devices movable in the guide-strips and on which the sash is mounted to swing, and locking devices for holding the guide-strips inward against the pressure of the springs at the lower end.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
